CCSS.Math.Content.6.EE.A.1
The standard
Write and evaluate numerical expressions involving whole-number exponents.
Common Core State Standards for Mathematics · Expressions and Equations
What this standard means
Students need to read, write, and evaluate expressions with whole-number exponents, like 3^4 or 2 × 5^2. They should know the exponent tells how many times to use the base as a factor, not what to multiply the base by.
Mastery looks like writing repeated multiplication as an exponent expression and finding the value using order of operations. Common mistakes are treating 4^3 as 4 × 3, ignoring exponents before multiplication, or thinking 2^3 and 3^2 have the same value because they use the same numbers.
Ways to teach it
- Hands-on activity: Give students square tiles to build 2^2, 3^2, and 4^2, then record each as repeated multiplication and value.
- Discussion or writing prompt: Explain why 5^3 is not the same as 5 × 3, using numbers, words, and one example.
- Quick assessment: Ask students to evaluate 6^2, 2^5, and 3 × 4^2 on an index card before leaving.
- Real-world connection: Compare area models like a 10 by 10 garden to 10^2, then connect larger squares to powers.
